This invention pertains to preselecting mechanism.

It is an object of this invention to provide preselecting means forcontrol mechanism.

Another object is to provide preselecting means controlled byregistering mechanism, and controlling control means.

Still another object is to provide preselecting mechanism for operatingcontrol means, said mechanism being controlled by registering means, thecontrol means being conditioned to a predetermined position only whenthe registering means has been moved to a predetermined position. y

A further object is to provide preselecting mechanism for a liquiddispensing apparatus.

A still further object is to provide preselecting mechanism for a liquiddispensing apparatus wherein preselection may be made in either the costof the liquid to be dispensed, or the amount of liquid to be dispensed.

Yet a further object is to provide preselecting mechanism for a liquiddispensing apparatus controlled by the register of said apparatus.

Another further obiectis to provide preselecting mechanism for a liquiddispensing apparatus which positively prevents liquid from beingdispensed after the selected amount or cost of the liquid has beenregistered.

A still further object of the invention is to provide preselectingmechanism for a liquid dispensing apparatus wherein the mechanism iscontrolled by the register and wherein having once dispensed apredetermined amount of liquid, the liquid dispensing apparatus isrendered inoperative until the register has been reset.

With these and various other objects in view, the invention may consistof certain novel features of construction and operation as will be morefully described and particularly pointed out in the specification,drawings and claims appended hereto.

In the drawings, which illustrate embodiments of the device and whereinlike reference characters are used to designate like parts- Figure 1 isan elevation, partly in section, of a liquid dispensing apparatusprovided with preselecting mechanism embodying the invention;

Figure 2 is an enlarged side elevation of a registering mechanism suchas illustrated in the liquid dispensing apparatus shown in Figure 1.showing the connecting means for operating the preselecting mechanism;

Figure 3 is a fragmentary side elevation of a liquid dispensingapparatus casing showing the application thereto of one form oipreselecting device, the operating means thereof being shown ininoperative position;

Figure 4 is a vertical sectional elevation taken substantially in aplane through the shafts 524 and 264 of Figure 3, i. e., substantiallyin the plane as indicated by the line 4-4 of Figure 3;

Figure 5 is a sectional elevation through the preselecting mechanism,the same being taken substantially on the vertical center line oi'Figure 3, that is, in a plane through the shafts ist and |36;

Figure 6 is a fragmentary sectional bottom plan view showing a portionof the reset and selecting mechanism illustrated in Figure 3, the samelooking upwardly of said figure;

Figure 'i' is an elevation through a portion of the operating mechanismof the preselecting device, the same being taken substantially in theplane as indicated by the line 'I-l of Figure 4;

Figure 8 is a fragmentary sectional top plan. view of the preselectingmechanism looking downwardly on the mechanism illustrated in Figure 13;Y.

Figure 9 is a fragmentary elevation of the preselecting mechanism, thesame being taken substantially in the plane as indicated by the lin 9-9of Figure 4;

Figure 10 is an enlarged elevation through the fractional moneypreselecting pawl and ratchet;

Figure 11 is an elevation taken substantially in the plane indicated bythe line il-il of Figure 4;

Figure 12 is a fragmentary top plan view oi a portion of the fractionalcontrol mechanism illustrated in Figure 11;

Figure 13 is an elevation of a preselecting mechanism showing partsthereof broken away to illustrate the subtracting ratchet, the dialarrangements, and the selecting cam of the preselecting mechanism;

Figure 14 is a fragmentary elevation of the subtracting cam and portionsof the latch mechanism for the valve control plate;

Figure 15 is an enlarged fragmentary sectional elevation of thesubtracting pawl mechanism;

Figure 16 is an enlarged fragmentary sectional elevation through thevalve opening mechanism and valve plate 'control mechanism;

Figure 17 is an enlarged fragmentary elevation showingthe connectionbetween the valve operating shaft and the valve shaft;
